Best Instagram unfollowers apps for iPhone
Short answer
If you want a real App Store app that never asks for your password, UnfollowCheck is the pick: it works from your public profile, sends a push notification when someone unfollows you, and costs nothing to try. If your account is private or you don't want a subscription, UnfollowChecker reads your official data export instead: it runs in Safari with nothing to install, the count is free, and the full list is $2.99 once. FollowMeter and Followers Track need your Instagram login, which is why they sit at the bottom.
Search the App Store for "unfollowers" and you get two very different kinds of app wearing the same icon. The first kind asks you to sign in with your Instagram username and password, then logs in as you from its own servers to pull your lists. The second kind never sees your password: it either reads the data export Instagram gives you, or reads what is already public on your profile. On an iPhone the difference is invisible at install time and enormous afterwards, because the first kind is what produces the Action Blocked warnings and "suspicious login" emails that fill those apps' own reviews.
This list is ranked by that difference first and by features second, following the five checks on our how we test page. No-password tools come first. Within that tier we rank on what you actually get on an iPhone: a native app with notifications beats a web page if you want alerts, and a free export reader beats a weekly subscription if you only want the list once. Login apps are at the bottom with their honest advantages noted, because a live activity feed is a real feature, just not one worth a locked account.
One thing no app on this list can do is tell you who unfollowed someone else's *private* account. Tools that work from public data (UnfollowCheck, FollowSpy) need the profile to be public; export tools only work on your own account, public or private. If you want the shortest safe route on an iPhone without installing anything, the iPhone unfollow checker guide walks through the export in Safari step by step.

UnfollowCheck (unfollowcheck.com)
Logs in to Instagram on your behalf · Web, iOS
UnfollowCheck is a native iPhone app (also on iPad and Apple Silicon Macs) that tracks your own account by username rather than by login. You type your public handle, it reads what Instagram shows publicly, and from then on it compares snapshots and pushes a notification when someone unfollows you. There is a Home Screen widget, a doesn't-follow-back list, and a watchlist for up to three other public profiles. The web version at unfollowcheck.com is a cut-down companion; Android is listed as coming, with a sign-up form rather than an app.
It never asks for your password, which is the check that matters most, and because nothing logs in as you there is nothing for Instagram to block. The trade-offs are two. Your account must be public for it to see anything, so private accounts are out. And the full app is a subscription: the App Store listing shows a $4.99 weekly option, Pro bundles from $8.99 to $34.99, and a $79.99 lifetime unlock, with web Pro at $36 a year. Reviews mention being charged after a free trial the reviewer thought they had cancelled; the developer's reply is that trials renew unless cancelled 24 hours before they end.
Best for: a public account that wants an actual app with unfollow alerts and is happy to pay a subscription for them. See the UnfollowChecker vs UnfollowCheck comparison for the feature table, or the UnfollowCheck alternative page if the subscription is the sticking point.

UnfollowChecker
Works from your data export, no login · Web, any device
UnfollowChecker (this site) is not an app at all, and on an iPhone that turns out to matter less than you'd think. You request the export from Instagram, tap the ZIP when the email arrives, and open it on this page in Safari or Chrome; the comparison runs in the browser tab and the file never leaves your phone. The non-follower count and your followers and following CSVs are free, the two-export unfollowers comparison is free, and the full list of who doesn't follow you back is a one-time $2.99 with a $3 fans-and-mutuals add-on. No subscription, no account, no login.
We rank it below the two apps above for an honest reason: this page is for people searching for an *app*, and a Safari tab has no icon on your Home Screen and no push notifications. It also can't check anyone else's account and can't alert you to anything, because nothing is connected to Instagram. What it has over them is that private accounts work (the export doesn't care), it is the cheapest full list on this page, and there is nothing installed to go stale when Instagram changes something.
Best for: a private account, a one-off clean-up, or anyone who refuses to install another app. The iPhone walkthrough covers the Files-app step that trips people up.

FollowSpy
Scans profiles through Instagram's private API · Web, iOS
FollowSpy is a public-profile tracker with a web version at followspy.ai and a native iPhone app. Like UnfollowCheck it needs no login: enter any public username and it shows recent follows, new followers and unfollows in order, refreshed over time. The pitch is mostly about watching other people's accounts, but it works on your own just as well, and it never posts, follows or interacts on your behalf.
It is here because it passes the password check, not because it is cheap. The App Store lists weekly plans at $12 and $14 and quarterly plans at $109.99 and $127.99; the web plans are $7 and $9 a week, or a little less per week on a quarterly commitment. Private accounts can't be tracked at all, which reviews mention when someone pays and then finds the profile they wanted is private, and the iPhone app has only a handful of ratings so far.
Best for: someone who specifically wants to monitor a public account's follow activity over time and has the budget for a weekly plan. For your own non-followers it is overkill. Compare it with UnfollowChecker.

FollowMeter for Instagram
Needs your Instagram password · iOS, Android
FollowMeter has been in the App Store since 2013 and is the most downloaded name on this list, on both iPhone and Android. It asks you to sign in with your Instagram username and password inside the app, then shows unfollowers, ghost followers, story viewers and a live activity feed. The free tier shows a limited amount; Plus is $3.99 a week, $4.99 a month or $24.99 a year, Pro is a one-off $8.99, and extras such as Secret Admirers and Blockers are $1.99 packs.
The login model is what keeps it out of the top tier. Reviews mention "suspicious activity" warnings and temporary restrictions on Instagram after using it, forced sign-outs, and frustration that features that used to be free now sit behind the subscription. On the other side of the ledger, the live feed and follower history are real features that no export tool can offer, and they are the reason it still ranks above Followers Track.
Best for: someone who understands the risk and wants real-time unfollow history more than they want certainty about their account. If that isn't you, the FollowMeter alternative page and the FollowMeter comparison cover the switch.

Followers Track for Instagram (Reports+)
Needs your Instagram password · iOS, Android
Followers Track (listed as Followers Track & Likes Insight) is another sign-in app, with over 55,000 ratings on the App Store. After you log in with your Instagram credentials it lists non-followers, recent unfollowers, lost and new followers, inactive followers and engagement by post, and it supports multiple accounts. It runs a three-day trial and then charges $4.99 a month or $23.99 a year.
It is last because it combines the login model with the weakest review record of the six. Reviews mention "violated community standards" warnings on the connected Instagram account, non-follower data that stops updating after subscribing, login errors and crashes. The best-time-to-post charts are a nice extra for a creator account, but the core list is no more accurate than a free export.
Best for: hard to recommend over FollowMeter if you have already decided on a login app. Our Followers Track alternative guide and the Followers Track comparison cover what you keep and lose by switching.

How this list was made
Every app on this page was installed on a test iPhone with a throwaway Instagram account and run through the five checks described in how we test: whether it asks for your password, whether it calls Instagram's private API, what the latest App Store reviews report, what it actually shows, and what it really costs once the trial ends. We take no affiliate commission or payment from any app listed, we never test with a real personal account, and we don't give star ratings. Prices were checked on 12 October 2026 and change often; the App Store listing is the authority on the day you buy.
Frequently asked questions
What is the best Instagram unfollowers app for iPhone that doesn't need a password?
UnfollowCheck if your account is public and you want push alerts; UnfollowChecker in Safari if your account is private, you don't want a subscription, or you don't want to install anything. Neither ever asks for your Instagram login.
Can an unfollowers app get my Instagram account banned on iPhone?
Apps that sign in with your Instagram password can. They log in as you from their servers, which is what triggers suspicious-login warnings and action blocks. Apps that read your data export or your public profile never log in as you, so there is nothing for Instagram to detect.
Is there a completely free unfollowers app for iPhone?
Not a native one without a subscription behind it. UnfollowChecker shows your non-follower count, your followers and following CSVs, and a two-export unfollowers comparison free in Safari; only the full non-follower list is paid, at $2.99 one-time.
Why doesn't Instagram just show who doesn't follow me back?
Instagram labels accounts that follow you (Follow back) but never the reverse. The only official source is your data export, which contains both lists. Export-based apps compare them; login apps scrape the same lists by signing in as you.
Do these apps work on a private Instagram account?
Export-based tools like UnfollowChecker work on private accounts because the export contains your lists either way. Public-data tools (UnfollowCheck, FollowSpy) can only see public profiles, so a private account shows nothing.
